How to automatically update an application installed with Inno Setup

问题

I have an executable application setup.exe for Windows that I realized with Launch4j/Inno Setup based on Java.

I often frequently release new versions and bug fixes.

I would like to know if there is a mechanism to install updates automatically?

回答1:

Inno Setup does not have any built-in mechanism for implementing automatic updates.

You need to implement that yourself:

• Make your application check for new versions (against your application webpage?). E.g. on startup (on a background thread?)
• If the application detects a new version, make it download an installer to a temporary location.
• Make the application execute the downloaded installer. You can make the installer run in silent mode (/silent switch). The application should close itself, to unlock any files it is using, to allow files update.
